Integrating 3D printing parameters into technical drawings: a framework for seamless additive manufacturing

Resumen

Additive manufacturing (AM) has transformed industrial production through complex geometries, rapid prototyping, and customization. However, a major challenge remains: the limited integration of AM-specific parameters into technical documentation, causing inconsistencies between CAD models and manufacturing execution.

This study proposes a standardized framework for embedding key 3D printing parameters—such as layer height, infill density, extrusion temperature, and support structures—into CAD-based technical drawings. The framework introduces a structured annotation system, akin to geometric dimensioning and tolerance (GD&T), to improve communication and interoperability across design and production stages.

It includes a dedicated layer for AM-specific attributes like infill patterns, bead orientations, and perimeter definitions, essential for mechanical integrity and manufacturing efficiency. Aligned with international standards (ISO 7200, ISO 129, ISO 1101, etc.), the framework also specifies printer types, material properties, and test requirements.

By integrating these parameters into technical drawings and metadata, the methodology enhances precision, reduces errors, and supports the industrial-scale adoption of AM.
